Collapsible Menu/Website -- Problems

programming flash
1

I have a collapsible menu style website.

When I had a new nav item, it doesn’t butt up flush with the other menu items and I can’t figure out where the gap is coming from.

import mx.transitions.Tween;
import mx.transitions.easing.*;
_global.slidingMenu = this;
big_height = 336;
small_height = 64;
small_height_over = 30;
time_for_animation = 25;
time_for_animation2 = 25;
// Initialization
box1.id = 1;
box2.id = 2;
box3.id = 3;
box4.id = 4;
box5.id = 5;
for (var i = 1; i<=5; i++) {
    this["box"+i].title_main.area.onRelease = function() {
        slidingMenu.moveBoxes(this._parent._parent.id);
    };
    this["box"+i].title_main.area.onRollOver = function() {
        slidingMenu.RollOverBoxes(this._parent._parent.id);
    };
    this["box"+i].title_main.area.onRollOut = this["box"+i].title_main.area.onReleaseOutside=function () {
        slidingMenu.RollOutBoxes(this._parent._parent.id);
    };
}

slidingMenu.RollOverBoxes = function(boxNumber:Number) {
    if (_root.link<>boxNumber) {
        var cBox:MovieClip = eval('box'+boxNumber);
        cBox.title_main.gotoAndPlay("s1");
        for (var i = 1; i<=5; i++) {
            var cBox:MovieClip = eval('box'+i);
            ykoord = cBox.my_y;
            if (i<>boxNumber) {
                if (i<boxNumber) {
                    new Tween(cBox, "_y", Back.easeOut, cBox._y, ykoord-small_height_over, time_for_animation2, false);
                    cBox.my_y = ykoord-small_height_over;
                } else {
                    new Tween(cBox, "_y", Back.easeOut, cBox._y, ykoord+small_height_over, time_for_animation2, false);
                    cBox.my_y = ykoord+small_height_over;
                }
            }
        }
    }
};
slidingMenu.RollOutBoxes = function(boxNumber:Number) {
    if (_root.link<>boxNumber) {
        var cBox:MovieClip = eval('box'+boxNumber);
        //cBox.title_main.gotoAndPlay("s2");
        cBox.title_main.gotoAndPlay(cBox.title_main._totalframes-cBox.title_main._currentframe);
        for (var i = 1; i<=5; i++) {
            var cBox:MovieClip = eval('box'+i);
            ykoord = cBox.my_y;
            if (i<>boxNumber) {
                if (i<boxNumber) {
                    new Tween(cBox, "_y", Back.easeOut, cBox._y, ykoord+small_height_over, time_for_animation2, false);
